Pirate Treasure Mystery

Bought this for my 8 year old grandson. He loved it and looked forward to the coded letters each week. When the treasure chest finally came, he thought it was awesome and wanted to take it to school for show and tell.

My granddaughter said she would give it 300 on 5!

What a fun experience instead of just gifting them a toy. There was the sense of accomplishment as well as many little treasures along the way!

11 year old is highly engaged!

I bought this for my grand nephew's 11th birthday. He's a bright, thoughtful, creative boy who loves to read. His mom sent photos of him working very seriously, with his highlighter in hand, and studying the clues. It's a very satisfying gift in so many ways. I'm so pleased!

A huge hit with the Grandkids

I bought this for my grandson for Christmas and was his best gift ever. Also allowed me to spend quality time having a blast, being challenged and testing our skills all at the same time. I would definitely buy again and highly recommend you do it together!
